same time, light in Weight, and easy to manufacture at e moderate price. This object 'is etta ined by constructing the ring of two identical parts Which are placed side by side end secured to each other by means of lugs integral with, and alternately projecting from the edges of the ring parts and which,

when bent down over the other conti uous ring part and folded together with their lateral Wing's, tightly clamp the two rings together. The said lugs or projections which by their folding are given at U-shape also form the spacing pieces cxtending'between, and spacing the balls of each series. The recesses on either side of the ring are preferably rounded out to adapt the periphery of the balls to be received. by them. T this end the two rings are undulating or sinuous on their sides, and the recesses formed on these sides between the single lugs are accordingly arranged in :1 staggered relation.

In the drawing which forms a part of this specification, an embodiment of the invention is illustrated by Way of example.

, Figure 1 represents, partly in cross-section, an annular ball-bearing of usual construction With two series of balls and the spacer-ring mounted therein. Fig. 2 is a sit e-elevation of the said beaming and spacerrino'. Fig. 3 is an outer view of the spacerring alone. Fig. partly represents the two ring parts which form the spacer-ring, illustrating the single operation of bending and folding the lugs. Fig. 5 is a perspective view Like reference throughout all figures of the drawing.

- The spacenring which can be used in ballbearings of any usual construction with two series of balls and any suitable boll-tracks or races, such as cylindrical, conical, spherical, or grooved races (Figs. 1 and 2 illustrate letters denote like parts the latter arrangement), is composed of the tu'orings a and b of congruent form; the said rings are, for example, undulated on their sides or sinuous in axial direction and are placed with their fiat sides against each other, in which position they are in close contact throughout the entire circumference, as the undulations of one ring conform to the corresponding undulations ot' the other ring. This tight fit will best be seen from Figs. 1, 3 and Projecting from the outer edges of either ring a and b are lugs c which are conncctedv with the corresponding ring body only by the comparatively small strip (Z, While their sides are enlarged in opposite directions, so

as to form Wings 7' (Fig. l). The said lugs r; of either ring are bent down over the outer edge of the other ring, that is to say, the said lugs oi the ring a are bent over the ring 7) and vice verse, so that they project in opposite directions from the central body, and their wings f are folded'radially inwardly, whereby their inner edgesbear against the lateral face of the other ring, while the longitudinal edges of said Wings converge toward each other. By this construction of the lugs 0 which are the spacing means for the balls and are arranged alternately upon the two sides of the ring-body (I, and 7) in staggered relation, U-sl' aped and radially extending members can be formed of any suitable length for passing through between two consecutive balls, as shown in Figs. 1 and 2.

The central double body of the spacer: ring can be formed of two plane rings, but preferably the said rings are undulating, as shown in the example, and the strips (Z are formed on the depressions of the corresponding ring, so} that the lugs 0 are located upon the elevations of the other ring, as clearly represented in Fig. 3. This shape of the central body in connection with the rounded sides of the lugs 0, will more perfectly conform the Wells of the recesses between tWo lugs to the periphery of the balls therein received and guided (Fig. 5). Moreover, it is obvious that the construction Will not be altered, if the lugs are in connection With the inner edge 0t one or both rings a and b, or alternately with the outer and inner edges;.these modifications therefore do not require illustration. The lugs may also be of any desired height and at their free extremity as bread as is suitable for holding the balls.

' nite shape.

v wings f of all lugs c are folded toward each other, whereupon the rings are placed the one against the other'in such a manner that the lugs of either ring alternately project over and beyond the edge of the other ring. When the lugs are then bent down upon the side of that other ring a secure connection of the structure is obtained, while the rings a and b are tightly held together. If the lateral dimension of the lugs 0 is reduced or the distance between the single lugs increased, the assembling of the-two rings may be effected after the erection of the lugs 0, as shown in the middle part of Fig. 4, and when the rings are joined, the wings f are finally folded together.

The composition of the spacer-ring of two symmetricalrings not only has the effect to strengthen the central part of the spacer \by doubling its thickness, but also insures the cheap and easy manufacture of the construction, The special double arrangement of the lugs produces rigidityof the connection and a certain yieldingness of the wings which will favor the smooth and noiselessrunning of the balls.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A spacer-ring for ball-bearings with two rows of balls, composed of two rings having lugs projecting from the edges of either-mingxover the other ring so as to clamp the said rings together, also forming spacing means for the balls.

2. A spacer-ring for ball-bearings with two series of balls, comprising two rings and lugs projecting from the edges of either ring and bent down upon the side of the other ring, the said lugs being so formed as to be the spacing means for the balls.

3. A spacerring for ball-bearings with two series of balls, comprising two congruent rings placed side by side, lugs proj ecting from the edges of either ring beyond the other ring, and wings of the lugs folded together and bearing upon outer side of the other ring.

4. A spacer-ring for ball-bearings Wlth two series of balls, comprising two sinuous rings placed side by side, lugs projecting from the edge of either ring over the other ring, and wings of the lugs folded together alongthe elevation of the other side of the spacer-ring, the sides of the lugs being hollowed out so as to conform themselves to the periphery of the balls to be received in the interstices between every two lugs.

5. The combination withv a ball-bearing having two rows'of balls, of a spacer-ring, comprising two rings placed side by side and situated between the two rows of balls, and lugs projecting from the edge of either ring over the outer side of the other ring, so as to clamp the ring tightly together, and extending between wo consecutive balls for spacing same.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. i
